Heh.. I really haven't figured that out. The display just seems to jump around with no pattern/algorithm that I can recognize. At the moment, it's useless to me for zooming in on anything other than a repetitive waveform, unless I can capture it again at the higher zoom level.

I've got to read through the documentation again, and figure out what all of the little on-screen indicators represent, and then figure out what's buggy and what isn't.

Cheers
